We spend a ton of time, and massive sums of money, researching the major diseases/killers: cancer, diabetes and heart disease.
Which isn't a bad thing, for obvious reasons.
That said, there is something I don't understand, and that is that by FAR the biggest risk factor in all the major killers is age: Cancer is quite rare in people younger than 30, and the risk increases dramatically for the next 30 years of life. The same is true for heart disease, as the risk of CVD is very low for persons under 30, and actually increases 7 fold from 45 to 75.
With that in mind I fail to understand is why almost no money is allocated then to the preventative approach: Geroscience/senescence (aging) research. It's great to learn how to treat the disease once it is there...but why are we making essentially no effort to preventing CVD/cancer/diabetes in the first place?
